Hi guys i just wanted to know if it is normal for plants to melt and go brown.My tank has been setup for 3 days now and iv started to notice the symptoms there is no algea at the moment.Is it normal for plants to do this? My tank is a 6g edge,ada substrate and powersand with all the nutrients i am also dosing ei, my co2 and flow is good as i have upgraded the filter impeller with the aqua clear 50 impeller rated for 200gph plenty of movement in plants my lights are on 5 and half hours.c02 comes on 2 hours before and turns off 1 hour before lights out,drop checker is yellow at lights on and for some reason it stays yellow.i have changed the bromo blue water 3 times but drop checker stays yellow is there something im doing wrong?
